Technology frontier — CATL TENER Stack & the density race
CATL's TENER Stack is a 9 MWh grid-scale system launched at ees Europe (May 2025) — a stacked, two-in-one configuration of half-height units, each under 36 tonnes, engineered specifically around global road-transport weight limits. It builds on the 6.25 MWh TENER platform and its five-year zero-degradation claim, lifting energy per container footprint by ~50%.
The cell race has moved past 314Ah: 587Ah-class ultra-large cells are the industry's primary development focus, though integrators remain in wait-and-see mode on which format standardises. Every jump in cell size compresses $/kWh at system level — and widens the technology gap for anyone outside China's supply chain.

Who's who — Cat-1 vs Cat-2 cell/system OEMs & India availability
Cat-1 here = gigafactory-scale, bankability-grade OEMs that clear lender/insurer diligence in Indian utility tenders. Cat-2 = credible challengers that win on price or niche but need wrapping (LDs, insurance, balance-sheet support) to be financed. Availability in India is shaped less by the OEM's appetite and more by Beijing's export-control posture and India's trusted-vendor screening.

India Inc's cell retreat — JSW stalls, Reliance pivots to sodium-ion
JSW Group has put its proposed 50 GWh Odisha cell plant on hold — leadership says LFP cell technology is 'tightly guarded by China and unavailable elsewhere', pushing the group downstream into cell-to-pack assembly for BESS and EVs. JSW has meanwhile signed an MoU with RJE Tech (Rongjie Energy) for 5 MWh and 6.26 MWh ESS systems built on RJE's 314Ah and 588Ah LFP cells — buying systems while cell manufacturing waits.
Reliance's licensing deal with Hithium collapsed after Beijing tightened export controls on sensitive clean-energy technologies (Jan 2026). Reliance has since pivoted from cell synthesis to containerised BESS assembly at Jamnagar, procuring components from CATL and others — while accelerating sodium-ion work: no Chinese LFP licence needed, domestic soda-ash feedstock, and better tolerance of Indian ambient temperatures than NMC.
The pattern repeats across India Inc (Adani included): retreat from upstream cell chemistry to system integration, because non-Chinese technology routes are costlier and slower than PLI milestones assumed.
Why the China wall is real
▸LFP cell IP, precursor know-how and manufacturing equipment are export-controlled by Beijing
▸India imports effectively 100% of grid-scale cells; graphite/anode chain is equally China-dominated
▸VGF-supported projects need ≥20% domestic content — met today via containers, EMS, PCS & BoP, not cells
▸Developers optimise duty via AIFTA routes (Malaysia/Indonesia) — a workaround, not a fix
▸Every large-format cell generation (314Ah → 587Ah) resets the catch-up clock for Indian fabs

The EMS layer — who controls the brain (and why origin matters)
The EMS decides dispatch, SoC strategy, curtailment response and market bidding — it sees every telemetry point in the plant. That makes EMS origin a cybersecurity and sovereignty question, not just a software choice. CEA's cyber regime effectively pushes critical-grid operators toward auditable, India-resident control layers.

Net effect: imported cells are tolerated, but imported control layers (BMS/EMS with offshore telemetry) are increasingly not. Compliance-ready, India-resident EMS is becoming a tender differentiator — which is precisely where Indian software players can win before Indian cells exist.

Anyone underwriting 'domestic cells by 2028' into a bid is taking technology-transfer risk that JSW and Reliance have already repriced.

India's BESS Buildout Accelerates: 45-50 GWh Target by FY28 Faces Cell Supply Test
Crisil and CareEdge project massive battery storage capacity additions through FY28, but domestic cell manufacturing gaps and INR 4 lakh crore funding needs could determine execution pace.
Crisil Ratings projects India will commission 45-50 GWh of BESS capacity across FY27-FY28, marking a step-change from current deployment levels [1,3,4,7,8,18,19]
CareEdge Ratings estimates INR 4 lakh crore (~$48B) financing requirement for storage infrastructure through FY32, signaling capital-intensive scale-up ahead [5]
Domestic manufacturing push is underway but cell dependence remains the key bottleneck per SMM analysis, exposing supply chain vulnerability [2]
Active project pipeline includes NTPC's 200 MW/400 MWh Maharashtra tender, SJVN's 265 MW Haryana bid, and APPCC seeking 1,000 MW/4,000 MWh from commissioned assets [9,10,13,14]
NLC India is diversifying into BESS and exploring pumped storage consultancy, reflecting PSU diversification into storage beyond core generation [6,15]
Capacity Trajectory: From Pilot to Scale
Multiple reports citing Crisil Ratings converge on a consistent projection: India's BESS capacity will jump to 45-50 GWh by FY27-FY28, a significant leap from today's nascent base [1,3,4,7,8,18,19]. This repeated coverage across outlets underscores growing analyst confidence in the storage ramp-up trajectory, likely driven by falling battery costs, renewable integration mandates, and grid balancing needs as solar-wind capacity additions continue to outpace storage as noted in broader capacity trend coverage [16]. However, the headlines provide capacity projections without granular breakdowns on standalone versus co-located BESS, or state-wise distribution, limiting depth of analysis on where this growth will concentrate. The consistency across CareEdge and Crisil signals institutional alignment on India's storage inflection point, though execution risk from manufacturing and grid integration remains understated in current commentary.
Manufacturing Push Meets Cell Dependence Reality
SMM's analysis highlights that India's BESS manufacturing ecosystem is accelerating, yet cell dependence—likely on imported lithium-ion cells from China and other markets—remains the critical bottleneck [2]. This tension between domestic assembly capability and upstream cell sourcing mirrors challenges seen in India's broader battery and EV supply chains. The headline set includes GFCL EV Battery's Q1 FY27 concall analysis, suggesting domestic players are actively reporting on battery business performance, though details are limited [12]. Without deeper localization of cell manufacturing, India's 45-50 GWh ambition could face import cost exposure and geopolitical supply risk. The article's framing as a 'key bottleneck' suggests this is a structural constraint policymakers and manufacturers must address to de-risk the storage buildout timeline.
Financing Scale and Institutional Capital Needs
CareEdge Ratings quantifies the financing challenge: India needs INR 4 lakh crore for storage by FY32 [5]. This figure signals the scale of capital mobilization required—spanning debt, equity, and blended finance—to support the storage transition alongside solar and wind capacity growth. The headline does not break down funding sources or the split between public and private capital, nor does it address whether this figure covers standalone BESS, pumped hydro, or both. Given parallel PSU activity—NLC India's consultancy tender for pumped storage [15] and its expanding BESS portfolio [6]—it appears public sector entities are positioning to capture a share of this investment wave, potentially alongside private developers responding to NTPC and SJVN tenders [9,10,13,14].
Tender Activity Signals Near-Term Deployment
Concrete tender activity provides evidence of near-term momentum: NTPC has invited bids for a 200 MW/400 MWh BESS project in Maharashtra [13,14], while SJVN launched bidding for 265 MW battery storage in Haryana [10]. Separately, APPCC is seeking 1,000 MW/4,000 MWh from already-commissioned BESS projects [9], suggesting demand-side integration efforts are catching up with supply additions. These tenders collectively represent a mix of MW/MWh ratios (roughly 2-hour duration systems), consistent with grid balancing and peak-shifting use cases rather than long-duration storage. The geographic spread—Maharashtra, Haryana—indicates multi-state procurement rather than concentration in traditional renewable-heavy states like Rajasthan or Gujarat, though the headlines don't clarify whether this reflects a broader national rollout pattern.
So what: For developers, tender volume signals genuine near-term offtake opportunity, but cell import dependence raises cost and delivery risk. DISCOMs face integration timelines that may outpace grid-readiness. Lenders should scrutinize INR 4 lakh crore financing gap allocation and manufacturing localization progress before committing to long-tenor project debt.
